Water filtration technology has improved a lot over the years, offering new ways to clean our drinking water. However, there are many people who still rely on the old method of boiling water. It’s a habit passed down through generations, especially in places where clean tap water is not always available. Boiling water can kill germs, bacteria, and viruses, but when it comes to PFAS, it’s often not the solution. PFAS are forever chemicals, and if you wonder, can boiling water remove them? The short answer is no.
What is PFAS?
PFAS stands for per- and polyfluoroalkyl substances. These man-made chemicals are used in many products, such as non-stick pans, waterproof clothing, food wrappers, and firefighting foam. Their purpose is to help these products resist water, oil, and stains. But what’s the concern with them? Well, they don’t break down easily and can stay in the environment and even in your body for a long time. That’s why they’re known as forever chemicals. Long exposure to these chemicals may lead to several health issues over time.
How Do They Get Entered in Normal Drinking Water?
PFAS can enter drinking water from several sources. As these chemicals are used in many industries and products, they can spread into the environment easily. And once they get into the water supply, it becomes hard to remove them. Moreover, they don’t break down naturally in sunlight, air, or water, and they’re too small to be filtered out by regular methods. Below are the sources from which PFAS can get into the drinking water:
Factory Waste: We know there are many factories in the U.S.A. that manufacture products like non-stick pans, stain-resistant fabrics, waterproof clothing, and food packaging. When equipment gets washed or cleaned in these factories, the leftover chemicals can be flushed out with wastewater. If this waste isn’t properly treated, the chemicals can leak into nearby rivers, lakes, or groundwater, later becoming part of the drinking water supply.
Firefighting Foam: PFAS is a main ingredient in a type of firefighting foam called aqueous film-forming foam. When this foam is sprayed on the ground during training or emergencies, PFAS chemicals can soak into the soil and slowly reach underground water sources.
Landfills and Wastewater Treatment Plants: When you throw away products that contain PFAS, they often end up in landfills. When rainwater flows through the landfill, it can carry PFAS chemicals with it, which creates a toxic liquid. That liquid can then seep into the ground or enter wastewater treatment plants. This further becomes the reason for chemicals in rivers, lakes, or reused water.
Now, coming on, does boiling water remove PFAS?
No, boiling water does not remove PFAS. In fact, it might even make the problem worse. Here’s why:
When you boil water, the water turns into steam and evaporates. So, when some water evaporates, the PFAS stay behind because they do not evaporate or break down at boiling temperatures. In fact, as the water boils away, the PFAS become more concentrated in the water that’s left. Boiling is great for killing bacteria and viruses. But for PFAS, they need a different method for removal.
Why Doesn’t Heat Destroy PFAS? I know you might be getting this question into your mind, but let me be clear: PFAS are very strong chemicals which keep the molecules together even under high heat. Boiling water only reaches about 100 degrees Celsius (212 degrees Fahrenheit), which is hot enough to kill bacteria and viruses but not nearly hot enough to destroy PFAS.
If not boiling water, is there any other way to remove PFAS? Yes, there are a few methods that may help reduce PFAS in your water, such as:
Activated Carbon Filters: Certified carbon filters can effectively reduce the presence of PFAS chemicals.
Reverse Osmosis Systems: One of the best ways to remove PFAS at home. It works by pushing water through a very fine membrane that can block many contaminants, including PFAS. While they are effective, they are more expensive.
Ion Exchange Filters: These filters swap harmful ions like PFAS for safer ones. They’re often used in water treatment plants but are available for home use, too.
What to Do If You Find PFAS in Drinking Water?
- Don’t panic; here are a few steps you should take:
- Stop drinking tap water until you have a proper filter installed.
- Use bottled water for drinking and cooking if possible.
- Install a certified filter that effectively removes PFAS.
- Talk to local officials or environmental agencies, as they may have solutions or resources.
- Stay updated on PFAS regulations and safety tips in your area.
Final Thoughts
In the end, while boiling water is a good way to kill germs, bacteria, and viruses, it’s not useful for removing PFAS. These chemicals are very strong and stable, having many bad effects on your health. If you’re concerned about PFAS in your water and want an effective solution to treat it, consider installing a certified filtration system for it rather than relying on boiling water.
